Fever among outpatients with advanced human immunodeficiency virus infection.

Overview

BACKGROUND: Fever is common among persons with human immunodeficiency virus (HIV) infection. However, the clinical implications of fever in this population have not been evaluated. We therefore undertook a prospective study of fever in persons with advanced HIV infection to determine the incidence and etiology of fever in this patient group. METHODS: Prospective natural history study of 176 patients with advanced HIV infection followed up at Memorial Sloan-Kettering Cancer Center, New York, NY, from April 1, 1990, through December 31, 1990. RESULTS: Fever occurred in 46% of patients. A diagnosis was made in 83% of episodes, with acquired immunodeficiency virus-defining illnesses accounting for half of the diagnosed cases. Patients whose conditions required more than 2 weeks to diagnose most often had lymphoma, Mycobacterium avium-intracellulare bacteremia, or Pneumocystis carinii pneumonia. Four patients had persistent unexplained fever without a clear source. Only one patient had fever that clearly responded to antiretroviral therapy. CONCLUSIONS: Fever is common among outpatients with advanced HIV infection. Human immunodeficiency virus itself is rarely the cause of fever in such patients; the cause of the fever should be thoroughly evaluated.
